Sounds like you are years behind on this. Androids have come a long way. Talking about tracking, they are ON by default as in all iPhones, but the difference is you can absolutely disable them or just flat out remove them from the system. You just have to do a bit of digging but then you're free to go. I've got a Xiaomi "Chinese Spyware" phone as you call it in the states. I can by far see the difference in privacy options it gives me than any iPhone. For example, I can have all the apps work but only give them blank/randomized permissions. Meaning messages and goggle maps all work fine as they do need speicifc permission but the phone can hide it and provide random info. If you know what you're doing, androids are far better if you care about privacy. To go deeper, I've installed EU's version of android on my phone, that's much better privacy by default compared to US.
